1.Uses removable A4988 or DRV8825 compatible stepper drivers.
2.The extension board can be used for carving machine,
3 d printer driver expansion board
3.GRBL 0.8 compatible.
(Open source firmware that runs on an for Arduino UNO that
turns G-code commands into stepper signals)
4.PWM Spindle and direction pins,4-Axis support (X, Y, Z ,
A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins D12 and D13)
5.Compact design. Stepper Motors can be connected with 4 pin molex connectors or soldered in place.
6.Please note that this is an unassembled kit and Basic soldering skills are needed.
